Default Re: Removing Trojan GAC_32/64 in desktop.ini

Java(TM) 6 Update 29 <--- uninstall outdated java.


Reboot your machine and install the most current and up to date version of Java available here at the below link:

Java Runtime 6



NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system

Attached is fixlist.txt
  • Save fixlist.txt to your flash drive.
  • You should now have both fixlist.txt and FRST64.exe on your flash drive.

Now re-enter System Recovery Options.
Run FRST64 and press the Fix button just once and wait.
The tool will make a log on the flashdrive (Fixlog.txt).
Please attach this to your next message. (How to attach)

Now attempt to boot normally.


Download and run OTM.

Download OTM by Old Timer and save it to your Desktop.
  • Right-click OTM.exe And select " Run as administrator " to run it.
  • Paste the following code under the area. Do not include the word Code.

Code:
:Files
C:\Windows\assembly\GAC_32\Desktop.ini
c:\windows\assembly\gac_64\desktop.ini
C:\Windows\system32\consrv.dll
C:\Windows\8455191.exe
C:\Windows\8455191.dat
C:\Windows\system32\CE3.dll

:Commands
[emptytemp]
[Reboot]
  • Return to OTM, right click in the Paste List of Files/Folders to Move window (under the yellow bar) and choose Paste.
  • Push the large button.
  • OTM may ask to reboot the machine. Please do so if asked.
  • Copy everything in the Results window (under the green bar), and paste it in your next reply.

NOTE: If you are unable to copy/paste from this window (as will be the case if the machine was rebooted), open Notepad (Start->All Programs->Accessories->Notepad), click File->Open, in the File Name box enter *.log and press the Enter key, navigate to the C:\_OTM\MovedFiles folder, and open the newest .log file present, and attach the contents of that document back here in your next post.


Run FRST again like you did the first time and attach the log.


Now run the C:\MGtools\GetLogs.bat file by double clicking on it. (Right click and run as admin if using Vista or Windows7) Then attach the new C:\MGlogs.zip file that will be created by running this.

Let me know of any problems you may have encountered with the above instructions and also let me know how things are running now!

Now attempt to boot normally.



Download Combofix to your desktop. Do not run it by double clicking! See below.



Now we need to use ComboFix by sUBs
  • Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
    • If it is not on your Desktop, the below will not work.
  • Also make sure you have shut down all protection software (antivirus, antispyware...etc) or they may get in the way of allowing ComboFix to run properly.
  • If ComboFix tells you it needs to update to a new version, make sure you allow it to update.
  • Open Notepad and copy/paste the text in the below quote box. Ensure you scroll down to select ALL the lines:
Code:
KILLALL::

File::
C:\Windows\System32\CE3.dll
C:\Windows\304576.dat
C:\Windows\304576.exe
C:\Windows\assembly\GAC_32\Desktop.ini
c:\windows\assembly\gac_64\desktop.ini
  • Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
  • At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
  • You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
  • Now use your mouse to drag CFscript.txt on top of ComboFix.exe



  • Follow the prompts.
  • When it finishes, a log will be produced named c:\combofix.txt
  • I will ask for this log below

Note:

Do not mouseclick combofix's window while it is running. That may cause it to stall.

If after running Combofix you discover none of your programs will open up, and you recieve the following error: "Illegal operation attempted on a registry key that has been marked for deletion". Then the answer is to REBOOT the machine, and all will be corrected.


Now run the C:\MGtools\GetLogs.bat file by double clicking on it. (Right click and run as admin if using Vista or Windows7) Then attach the new C:\MGlogs.zip file that will be created by running this.

Default Re: Removing Trojan GAC_32/64 in desktop.ini

sorry for the late reply. I was away with work
done. attaching logs...
I think we succeeded as it wasn't detected in these past few minutes. will report back in a short while to confirm.

did I see correctly that some windows updates were uninstalled by combofix, or did I misread something?

Default Re: Removing Trojan GAC_32/64 in desktop.ini

Thankyou! I am glad everything is running normally again.

If you are not having any other malware problems, it is time to do our final steps:
  1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
  2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
    • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
    • "%userprofile%\Desktop\combofix" /uninstall
      • Notes: The space between the combofix" and the /uninstall, it must be there.
      • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
  3. Go back to step 6 of the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
  4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
  5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
  6. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
  7. Go to add/remove programs and uninstall HijackThis.
  8. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders
    related to MGtools and some other items from our cleaning procedures.
  9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
    • Refer to the cleaning procedures pointed to by step 7 of the READ ME
      for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
    • Then reboot and Enable System Restore to create a new clean Restore Point.
  10. After doing the above, you should work thru the below link:
